The following table should be used to determine the amount of propellant to be
off-loaded from a full condition to arrive at the indicated load. The allow-
able tolerance for the calculated off-load is ±0.5 pounds per weigh tank.
AI. Final tank pressure at overfill (PSIG)
BI. Propellant loading temperature (*F)
CI. Nominal overfill quantity (ib)
DI. Correction for tank pressure (Ib)
Fuel = 0.33 (Item A1 -40)
Oxidizer = 0.54 (Item A1 -40)
Correction for lording temperature (ib)
Fuel = 4.25 (Item B1 -65)
Oxidizer - -10.5 (Item B1 -65)
Measured density (GM/CC)
Nominal density (GM/CC)
Delta density (GM/CC) (Item F1 - Item GI)
Correction for measured density
Fuel - 8400 (Item HI)
Oxidizer - 8400 (Item HI)
Jl. Propellant in GSE
KI. Overfill quantity (CI+DI+EI+II+JI)
LI. Target loading
MI. Quantity required to fill RCS manifolds (APS only)
NI. Quantity to be off-loaded (Items KI-LI-MI)
NOTES:
ILoading temperature correction will always be negative.
2To calculate the nominal density solve the following equation where
T = temperature in *C of the measured density (usually 4"C for oxidizer
and 25"C for fuel). This equation is valid for 14.7 PSIA. Therefore,
the measured denisty must also be at 14.7 PSIA.
Nominal fuel density = 0.922904-0.0009377 (*C)
Nominal oxidizer density - 1.491539-0.0022832 (*C)
3Correction for measured density may be either positive or negative.
